In the embodiment of the present invention, all node devices of distributed system all safeguard there is location database, and this location database is for recording the corresponding relation between the information on services of this distributed system and service end position.Wherein, the corresponding relation between this information on services and service end position with of a database form recorded, can be stored in the location database of all node devices of distributed system.
As shown in Figure 1, the acquisition methods of this service end position specifically can comprise the following steps:
Step 101, node device, when providing first service, records the corresponding relation between the first service information of first service and the first service end position of first service in the location database of this node device.
Step 102, node device sends position storage resource request message with broadcast mode, carries the corresponding relation between first service information and first service end position in this position storage resource request message; In the location database of this other node device, the corresponding relation between first service information and first service end position is recorded by other node device receiving position storage resource request message.
In the embodiment of the present invention, node device receive other node device with broadcast mode send carry the position storage resource request message of the corresponding relation between second service information and second service end position time, then node device records the corresponding relation between second service information and second service end position in the location database of this node device.
Such as, distributed system comprises node device A, node device B and node device C.Node device A is providing HTTP (Hyper Text Transfer Protocol, HTML (Hypertext Markup Language)) when serving, in the location database of node device A, record the corresponding relation between service end position (the IP address as node device A) that the information on services (port information as HTTP service) of HTTP service and HTTP serve.Corresponding relation broadcast transmission between the port information that HTTP serves by node device A and the IP address of node device A is to node device B and node device C.Node device B (or node device C) records the corresponding relation between the port information of HTTP service and the IP address of node device A in the location database of node device B (or node device C).Again such as, node device A is receiving the FTP of node device B broadcast transmission (File Transfer Protocol, file transfer protocol (FTP)) corresponding relation between the port information of serving and the IP address of node device B time, then in the location database of this node device A, record the corresponding relation between the port information of FTP service and the IP address of node device B.
Step 103, node device, when needs use second service, utilizes the location database of this node device of second service information inquiry of this second service.Wherein, if record second service end position corresponding to this second service information in this location database, then perform step 104; If do not record the second service end position that this second service information is corresponding in this location database, then perform step 105.
